Belatedly add 2 entries relating to the introduction of scc(4) and

console if they upgrade without adding scc(4) to their kernel
configuration file.

The puc(4) driver has been overhauled. The ebus(4) and sbus(4)
attachments have been removed. Make sure to configure scc(4)
on sparc64. Note also that by default puc(4) will use uart(4)
and not sio(4) for serial ports because interrupt handling has
been optimized for multi-port serial cards and only uart(4)
implements the interface to support it.

The scc(4) driver replaces puc(4) for Serial Communications
Controllers (SCCs) like the Siemens SAB82532 and the Zilog
Z8530. On sparc64, it is advised to add scc(4) to the kernel
configuration to make sure that the serial ports remain
functional.
